To all whom it may concern:

Be it known that I, RICHARD JESCHKE, a citizen of the German Empire, andresident of Charlottenburg, in the State of Prussia, German Empire, haveinvented new and useful Improvements in Flooring Materials.

and Processes for Making Same, of which the following is a full,clear,and'exact speci- I realize a remarkable economy when com pared with theusual products. Further, my

product has the advantage that it is immediately ready for use and doesnot want as linoleum does, storing for a rather long period and drying,time, storing rooms and drying appliances being thus dispensed with. Mynew product is very tough and flexible or elastic, so that it is notnecessary to apply it to a lining of textile fabrics, paper or the likeas is necessary in the case of linoleum. However, if desired, such alining canof course be used;

- Accordin to my invention I first prepare two ingredlents, viz: (1) therubber-like product obtained by heatingglue or other glutinoussubstances or carbon hydrates with glycerin and (2) artificial resinsprepared by acting upon phenols and formaldehyde with alkalinecondensing agents, such as caustic alkalis or alkali carbonates. I thenmix these ingredients and heat the mixture until a tough mass is formed.While heating, a certain quantity of formaldehyde that has not enteredthe reaction, acts as a hardening agent. Other hardeningagents such aschromium salts, alum,"tannin' or the like may be added if desired, carebeing taken however in all cases to ensure a sufiicient elasticity ofthe product.

The productthus obtained can then be treated in the manner known'inconnection with linoleum by mixing it with cork meal v and kneadingand'rolling the mixture in the manner'well known to those skilled in theart. For cork meal I can substitute partly new product is distinguishedfrom.

or wholly other filling agents, such as wood meal or other finelydisintegrated cellulose.

If it is desired to obtain a coloured product, pigments 'may be added tothe mixture. If desired, the mass can be rolled upon a lining of paperor textile fabric but, as already mentioned, such lining is notabsolutely necessary.

For the glycerin used in preparing the first ingredient above referredto, other substances which are hygroscopic or prevent the mixture fromdrying may be substituted such substances being for instance potassiumsulfocyanate which may be-usedas an aqueous solution. I

-In practically carrying out-my process I can for instance proceed asfollows:

Example: I first prepare the two ingredients of the mixture. 200 grammesof glue or gelatine are allowed to swell ii -water and heated with 450grammes of glycerin for about 15 minutes ,up to about 90 C.

On the other band, 300 grammes of phenol bonate or the correspondingquantity of so- I dium carbonate or caustic soda solution for about10,1ninutes up to about 100 C. The artificial resin thus obtained ismixed with'equal'parts' of the mass obtained from glue and glycerin andthe mixtureis heated until a tough viscous mass is obtained. During thisheating a certain quantity of formaldehyde that has not enteredthe'reaction, acts. to hardenthe product.

" Instead of'carbolic acid other phenols,

creosote or the likemay be used.

I then take-18 parts by weight of the mass -so' obtained and Ilmix tliemwith 18 parts of cork meal or wood meal and if desired with 12parts'ofalpulverized pigment. The

pastous mass thus obtained is then kneaded and rolled inthe well-knownmanner.

. The proportions indicated may be modified according to therequirements of the special case and to the pro erties desired of theroduct to be obtalne ving thus described myinvention I wish it to beunderstood that I do not desir'e to limit myself to the exact detailsand proportions given, as obvious modifications will occur to personsskilled in the art What I claim is 1. The process of manufacturinglinoleumduring the last densing a phenol with formaldehyde by means ofan alkaline condensing, agent, heating the mixture until a tough mass isformed, adding a filling agent, and kneading and rolling the mixturethus obtained.

2. The process of manufacturing linoleumlike material, which processconsists in mix-4 ing the following two ingredients, viz the productobtained by heating glycerin with an organic compound, capable offorming a rubber-like product-by acting on glycerin, for producingtherewith a rubber like product, and an artificial resin obtained bycondensing a phenol with formaldehyde bymeans of an alkaline condensingagent, heating the mixture until a tough'mass is formed, adding ahardening agent during the last part of the heating process, then addinga filling agent, and kneading and rolling the mixture thus obtained.

3. The process of manufacturing linoleumlike material, which processconsists in mixing the following two ingredients, viz the productobtained by heating glycerin with a glutinous substance, and anartificial resin obtained by condensing a phenol with formaldehyde bymeans of an alkaline condensing agent, heating the mixture until a toughmass is formed, adding a filling agent, and kneading and rolling themixture thus obtained.

4. The process of manufacturing linoleumlike material, which processconsists in mixing the following two ingredients, viz the productobtainedby heating glycerin with a glutinous substance, and anartificial resin obtained by condensing a phenol with formaldehyde bymeans .of an alkaline condensing agent, heating the mixture until atough mass is formed, adding a hardening agent art of the heatingprocess, then adding a lling agent, and kneading and rolling the mixturethus obtained.

5. The process of manufacturing linoleumlike material, which processconsists in mixing equal arts by weight of the following two ingreients, viz the product '-0bta1ned by allowing 200 grammes of gelatine toswell in water and heating them with 450 grammes of glycerin up to about90 C. for about 15 minutes, and the artificial resin obtained by heatlng300 grammes of phenol with 300 grammes of a 35 per cent formaldehydesolution and 50 grammes of potassium carbonate up to about 100 C. forabout 10 minutes, heating the mixture of these two ingredients until atough viscous mass is formed, mixing 18 parts by weight of this masswith about 18 parts by weight of cork meal and about 12 parts by weightof a pulverized pigment and kneading and rolling the mixture thusobtained.

6. The herein described linoleum-like composition consisting of amixture of 200 grammes of gelatine with 450 grammes of glycerin and anartificial resin prepared from 300 grammes of phenol and 300 rammes of a35 per cent formaldehyde soution and 50 grammes of potassium carbonatewith an equal Weight of cork meal.

7 The herein described linoleum-like composition consisting of a mixtureof 200 grammes of gelatine with 450 grammes of glycerin and anartificial resin prepared from 300 grammes of phenol and 300 grammes ofa 35 per cent formaldehyde solution and 50 grammes potassium carbonatewith an equal weight of cork meal and approximately two-thirds of itsWeight of a pulverized pigment.

8. The herein described linoleum-like comproduct obtained by heatingglycerin with an organic compound, capable of forming a rubber-likeproduct by acting on'glycerin,

for producing therewith a rubber-like product, and an artificial resinobtained by condensing a phenol with formaldehyde by means of analkaline condensing agent, heating the mixture until a tough mass isformed, adding a filling agent, and kneading and rolling the mixturethus obtained.

In testimony, that I claim the foregoing as my invention, I have signedmy name in presence of two subscribing witnesses.
